Singletary got her Class A CDL license in 1960 and has kept it ever since. For the past 10 years she's taught at the institute. Before that she spend 20 years as the safety director instructor for Roadway Transportation.

The government hopes restricting hours will force drivers to take more down time and reduce crashes related to trucker fatigue.

"I don't necessarily believe that," says Singletary. She thinks that companies will be forced to compensate by putting more trucks on the road.

"It will cause more congestion, it will put more trucks on the highway because it takes away driving time," says Singletary.

Analysts project it will also create a demand for 100,000 additional truckers.

Singletary agrees, "I think it will cause a greater shortage. We have a shortage right now."

When the new rules go in to effect they'll also create more restrictions on how frequently long haul truckers must take breaks. But in most cases the number of hours they can drive for the day will remain set at 11, so long as they don't exceed 70 hours per week.
